On August 9, 1945, B-29 bomber Bockscar lifted off, carrying the nuclear weapon "Fat Man". Which city was it heading to?

Hiroshima

Nagasaki

Kokura

Moscow

The crew was under orders to only bomb vis­ual­ly. When they got to Kokura they found the haze and smoke ob­scur­ing the city as well as the large am­mu­ni­tion arsenal that was the reason for tar­get­ing the city. They made three un­suc­cess­ful passes, and even­tu­al­ly headed for Nagasaki and its torpedo factory, the al­ter­na­tive target. In Japan, the phrase "Kokura luck" was coined to describe lucky avoid­ance of the great mis­for­tune without being aware of it.
